Question #15: Since all hinges appear to be installed on the window trim and some hold opens are installed on wood blocks affixed to the siding, is the contractor expected to paint all window trim and wood blocks for the hold opens?

Answer: Are you referring to the current hinges and hold opens? If so, those will be removed, along with wood blocks. The hinges and hold opens are to be fabricated to look like the ones in Appendix 3.

Question #16: Section 4 Specifications L. touch up paint on sashes, siding and trim due to damage from shutter installation. So if no damage from the shutter installation occurs, no touch up in these areas is expected?

Answer: Correct

Question #17: Would a lift be required to access the second floor windows, would the contractor be able to step on the roof is needed, is the roof stable enough to support 1 worker approximately 200 pounds?

Attachment 1

Page 5 of 7 Pages

Answer: Yes. All of the shutters should be the same thickness

Question #31: Shutter hardware size - Off-set is what? Include screenshot of description. I reviewed all documents before attending the site visit, yet I assumed that would be a provided-for spec if we are custom-building the hardware.

Answer: Hinge offset is to be verified in the field by the contractor. Task # 3 requires a site visit to complete measurements of and verify required sizes for each opening. The hinges and offset must allow for the shutters to properly open and close without the use of additional wood blocks, like the ones that are currently being uses on the exterior. The current hinges and shutter dogs are not appropriate for this location.

Question #32: How close to the chemistry composition does a piece of hardware have to be to meet the spec as being custom-built?

Answer: Contractor may provide a submittal for the proposed metal, including the chemical composition. Provide a designation by testing agency, such as UNS, ASME, ASTM, etc.

Question #33: Shutter - verifying please that we don't need a tilt rod.

Answer: No tilt rod is required. Note that the louvers must be fabricated with the slant fixed away from the window opening when the shutters are in the closed position so that water won't come towards the window when it rains.

Question #34: Can work hours be expanded beyond 7a - 4:30p and what’s the process?

Answer: No

Question #41: During the 04/21/2023 Site Investigation, the on-site Park representative stated that Questions and Answers (Q&As) have occurred prior to the Site Investigation, and said that they will be posted onto Sam.gov. Will these other Q&As be posted as an amendment for contractor reference?

Answer: They are included in this list of questions.

Question #42: We respectfully request that the Site Visit sign in sheet be posted as an amendment.

Answer: That is not releasable information.

Question #43: The architect is saying to use Acme hardware. Typically, the Acme hinge is made from cast iron, which will not last more than a few years in the North Florida environment. Additional, the material specified is to be cast using an aluminum-bronze material. Our supplier has reached out and spoken with six separate vendors, and has not yet located any that are familiar with this material utilized in this application. Because of the relatively small amount of hinges required for this project, is does not seem likely that the manufacturer can justify a custom run. In reference to SOW Items g-I, is the Government open to contractor utilizing strap and pintle options?

Answer: No

Question #44: Reference Statement of Work, PMIS 320370, March 2023, 4. Specifications Item e): “ . . .

replacement wood for damaged wood at siding, window frames, and exterior trim:

Contractor is to submit a replacement material for all wood for the project, which is to have the characteristics of the original, old-growth wood. Replacement wood is to be dimensionally stable and long-lasting. Wood shall be highly rot-resistant and still workable for the specified repairs.”

Specifications Item k).: “The contractor shall fill holes, cracks, gaps with compatible patching material;

finish patch to match surrounding surface shape, texture and color. Larger repairs should be completed with replacement or a dutchman repair using a compatible wood match.”

There are areas of existing wood rot noted on a few windows along the sill (and around the window framework) that are not directly related to the replacement and installation of new shutters, hardware and hardware blocking, and are part of the window structural framework – they are not part of the trim.

Please clarify if the contractor is responsible to repair these areas that are not directly related and/or would be disturbed by during the execution of the shutter and hardware removal/replacement as noted in SOW k.?

Answer: If the hinges need to be attached to the frame then the frame should be repaired as a part of this contract. All wood repairs due to shutter and shutter accessory removal is a part of the contract.

Question #45: To clarify from the potential hardware manufacturer “ Silicon bronze screws and alloy is readily available. Don't understand the spec of aluminum bronze.” So depending on the answer to number #40 for the Acme shutter hardware, is it possible to change the hardware specs?

Answer: At this moment the hardware specs should not be changed.

Question #46: It was mentioned at the site visit that the windows were going to be replaced including any associated trim that was rotted. Is this going to be completed before the shutter project is started?

Answer: No. The windows project will be after the shutters project.

Attachment 1

Page 7 of 7 Pages

Question #47: If not, are we going to put the new shutters on the rotted trim or come back after the windows and trim are completed?

Answer: Refer to question #44.

Question #48: Will there be an area for a small dumpster?

Answer: Yes.

Question #49: Does the lawn area need to be protected from the lift?

Answer: Yes.
